The solution is $1\mathrm{.}74$m$,$ and $1\mathrm{.}66$ m$($NORMAL DEPTH$)$

In example Problem $6\mathrm{.}9,$ water depths were required at critical diversion points located at distances of $188,423,748,$ and $1,675$ m upstream of the dam. Depths were only found at locations $188$ and $423$ m upstream. Determine the depths of flow at the other two diversion points using the standard step method and a spreadsheet program. Has normal depth been reached in the last cross section?
